«Street art is the only art movement currently around; there are trends, sensibilities and groups of artists but street art is the only one that could really count as a movement due to its thousands of participants. To put it simply all the Surrealists could meet in a Paris café but you would need a stadium to fit all the street artists. Art movements are rare. There were only a few in the 20th century, perhaps, as few as two: modernism (the international style) and punk.
In 1910 someone might have asked: “why is there a high interest in modern art?” In 1979 someone might have asked: “why is there a high interest in punk?” Looking back the answers are obvious.»
